Abstract
The invention relates to a rubber wood impregnation treatment method, and belongs to the technical field of wood treatments, wherein a rubber wood impregnation treatment method is specifically designed. The method comprises: adopting a sodium chloride solution with a saturated concentration to carry out a soaking treatment on freshly-sawn rubber wood, and then carrying out a subsequent conventional drying treatment, wherein the surface of the rubber wood is immersed by the sodium chloride solution, and the solution maintains the saturated state during the soaking process. The treatment method has the following characteristics that: the treatment agent of the present invention is toxic and harmless, raw material cost is low, a process is simple, the existing mature traditional process can be used, production investment is low, and the treated wood has characteristics of no infesting, no mildewing, no blue stain, and no rot.
Description
Technical field
The invention belongs to the timber treatment technology field, the impregnation process method of a kind of rubber wood timber of specific design.
Background technology
Rubber wood timber refers to rubber tree timber.Rubber tree is a kind of tall and big tropical arbor, is taken as industrial crops and extensively plants in torrid areas such as Indonesia, Thailand, horse Song West Asia, India, Vietnam, Philippine, Cambodia, Sri Lanka and China south China because of producing natural rubber.The major product of rubber planting industry is a natural rubber, and byproduct is a rubber timber.
Rubber wood timber material ground is even, and color and luster is simple and elegant, and decorative pattern is delicate and pretty, and weight, hardness, intensity and toughness are moderate, easily dry, distortion, and machining property is good, is a kind of high-class timber.But owing to contain more rich carbohydrate, starch, protein etc. in the rubber wood timber, be easy to suffer infringements such as worm, mould and stain fungus, the natural life-span is very short, only just loses use value about 1 year.Therefore can not be used for the permanence material, and can only be used for the provisional materials of using such as fuel wood and building template, value is very low.In order to develop the rubber wood timber resource, researched and developed out some rubber wood timber guard technologies both at home and abroad once.
The rubber wood timber guard technology that uses in the existing domestic production is still also being continued to use external method of nineteen thirty-seven, promptly earlier with containing insect-proof agent borax (Na

2O) the aqueous solution carries out hot cold trap immersion treatment or vacuum pressed processing to virgin rubber plank square bar, will handle the timber stacking airing of doing then, or send into force drying equipment (facility).The technology similar to this method has Chinese patent, " rubber wood protective method " (01123437.7), " a kind of rubber wood timber wood chip anticorrisive agent and application thereof " (201110122532.9), " a kind of mould inhibitor of rubber wood timber and application thereof " (201110122531.4), " the anti-variable color protective agent of a kind of environment-friendly rubber wood mildew-resistant " (201210461647.5).
1., in the ordinary course of things can be not infested the protection effect that this technology is certain to having of rubber wood timber, but following defective is arranged:, but part timber also can be by the bark beetle erosion of damaging by worms during airing sometimes, and the moth erosion stops after the kiln drying, and the timber top layer stays many little worm channels; 2., most timber mildew not during the airing, minority president's mildew.The kiln-dried wood that dug is placed on indoor, mildew not during dry weather, president's mildew when rainy weather is moist day after day; 3., the timber top layer can variable color during the airing, but the internal layer of some timber can variable color.The timber of internal layer variable color color to the eye is normal, yet saw will expose after separating and black-and-bluely (is " blue stain ", be the result of stain fungus harm), with such products such as timber Hepplewhite, outward appearance fails to keep the natural colored of rubber wood timber, natural poor aesthetics, do not meet the phychology needs of advocating the contemporary consumer who goes back to nature, the market competitiveness is not strong, and market and price all effected suffer a loss the operator economically; 4., the toxicity of institute's with medicament: borax and boric acid is free from extraneous odour all, and people and animals' toxicity is respectively low toxicity～little poison and little poison, and is little to environmental disruption.But penta sodium pentachlorophenate has pungent odour, and people and animals are had moderate toxicity, and to the aquatile severe toxicity, environmental pollution is more serious, and some countries and regions has been forbidden or limited use.Owing to temporarily can not find the medicament that replaces penta sodium pentachlorophenate, the industry of China's rubber wood timber protection is at present also being used penta sodium pentachlorophenate.
Has toxicity in order to solve in the above-mentioned technology, to human body and environment adverse factors, Chinese patent literature discloses " a kind of method for comprehensively modifying rubber wood timber " (200910141859.3), this method is a physical method, has adopted the intensification of preserving moisture, high temperature drying, hot and humid modification processing and cooling damping to handle four continuous technologies rubber wood timber is handled.Though in a period of time, can realize anti-damaging by worms, mildew and blue stain, carbohydrate, starch, protein iso-metamorphism factor contained in the rubber wood timber can not be eliminated fully, the time is long slightly still also can be occurred.And this method complex process, the special equipment investment is bigger, can cause production cost higher.
Summary of the invention
In view of the problem that above prior art exists, the purpose of this invention is to provide a kind of impregnation process method of rubber wood timber, the inorganic agent that it uses is nontoxic, harmless, cost of material is lower, technology is simple, can still continue to use existing ripe traditional handicraft, and the production investment is lower.
Realize that the technical scheme that above-mentioned purpose of the present invention adopts is: the rubber wood timber of fresh saw being separated with the saturated concentration sodium chloride solution carries out immersion treatment, sodium chloride solution should flood the rubber wood timber surface, should keep solution to be in saturation state in the immersion, carry out follow-up conventional drying then and handle.
Impregnation process method of the present invention is for the virgin rubber timber of thickness 2～10cm, and the immersion treatment time is 2～30 days.When plank thickness is thin, temperature is higher, can the time when pressurization is soaked shorter, otherwise the processing time is long slightly.
The invention has the beneficial effects as follows: because the sodium chloride raw material sources are wide, cost is lower and nontoxic to human body, thus can improve working environment greatly, reduce production costs, and need not change existing ripe process route; Sodium chloride is to the rubber wood timber impregnation process, has that excellent preventing damaged by worms, mildew and a blue stain effect, has low cost, environmental protection, advantage of simple technology simultaneously again.
